Subway Shield Construction Risk Management

In recent years, with the rapid development of shield technology in China, security and quality accidents are total rendering clear upward trend in construction of shield, subway accident is occurred one after another in recent years raises attaches to risk management in construction of Metro shield, there is a need for risk management of Metro shield construction research.Risk control provides a variety of measures for construction of metro shield, which in the construction process to reduce or eliminate the risk occurs possibility, in the construction of a purpose of implementation and monitoring, will effectively avoid engineering accident, and can reduce the occurrence of project cost overruns and delays situation may be, to guarantee the smooth construction.With the combination of the risk management theory and the experience got from the metro projects, the paper detailed of content from Basic theory risk management and processes in subway shield construction, Subway Construction Risk Management model is established by AHP and fuzzy comprehensive evaluation, and combination Suzhou track traffic Line2line shield frame construction of risk factors for has risk recognition, and risk estimated and risk evaluation, and made corresponding of risk countermeasures to reduced construction risk, then through established risk guarantee system to completed risk monitoring, Finally cited several dangers encountered in the actual construction and the use of risk management theory has successfully dealt with risk, case illustrates the risk management certification system and risk management in real-world applications of construction, better addressing all kinds of risks you might encounter in the construction, has certain guiding significance for safety in shield construction.
